NCSoft put Aion 2 maintenance into effect on October 5, 2026, taking the servers offline ahead of the launch. The gates to Atreia were scheduled to reopen at 3:00 PM, and the downtime came as the server count was still moving upward.
By the time the maintenance window was being tracked, the servers were still stable and green, and most servers could still create characters. At the same time, the player count was rising fast, with Steam in Atreia showing about 215,117 players simultaneously active and the total on Steam gradually approaching 400,000 concurrent players.
NCSoft and Steam
NCSoft had already reported 400,000 players via Steam, while the article also said there were almost 300,000 concurrent players on Steam. That split in the numbers reflects two different ways of describing activity: a reported total and a live concurrent count.
For players trying to get in during the maintenance window, the practical issue was access, not account status. Free-to-Play players said Aion 2 was not displayed as playable, and restarting Steam or a PC helped some of them when the game still did not appear.
Atreia at 3:00 PM
The launch-day maintenance also came with temporary restrictions for new characters on some servers. Even so, the article said most servers remained green, which meant the main disruption was tied to the offline window rather than a wider outage.
For anyone waiting to play, the only firm next step was the scheduled reopening at 3:00 PM. After that point, the unresolved question was whether the game would show up normally for Free-to-Play players without another restart.
